VAPOR ELECTRIC APPARATUS- Appllcstinn am my 31, n.

-son, a subject of the King of Greet Britain,

fto protec't t the blast or 'residin at Schenectady, county of Schenectad y, S tete of New York, have invented certain new and useful-Improvements in Vapor Electric Apparatus,- of which the following is a s ecificetion. V y present invention relates to certain improvements in vapor electric devices, such. as mercury-lam s, rectifier-s, or the like. Among otlier features my invention eims he solid electrodes or anodes from draft of vapor in the envelo Disintegration of the anodes is thus lsr cl; revented, and at the same time the blac ening' orl'the glass envelo /of the lamp is either decreased or entirely e iminatcd. II he features of novelt characteristic of my invention are pointer out with particularity in the appended claims. The inven-; ,tion itself, however, will be better understood by reference to the following description,

- taken in connection with the accompanying drawings, in which Figure 1 represents one embodiment of my ;invention, and Fig. 2 a modification.

my invent sq surmounted bar (lensing-chem The mercury-lamp to which I have shown ion as applied inFig. 1 consists of e or envelop 1, of suitable length,

ebulb 2, constitutin a coner. The bcttoni of t e tubed, as at 3;:md is surrounded b a glass tub 1 .is contracte a solenoid}. A body. of mercury 5 fills the upon its reappearsn contraction 3, as well es, the lower end of, the tube 1, as'shown, and, constitutes one of the electrodes of the lamp." A lesdingdri conductor 6' makes electrical connection with. this body of mercury and is in turn connectcd'in series with the solenoid 4. A core 7 of ironcup'ped outlet its upper end floats in the body of mercury and is urrn'nged as indicated in'dotted lines within the influenceof the solenoid 4.- After the core has-been once submerged its upper end bri with it a. quantity of mercury 8, llin t ecu in the upper end of the core. This ody o mercury 8 when the core is in the-positmnshown embraces the lower end of a carbon'or similar filament 9. This filament 9 is supported from the carbon or grephite anode 10 of the lamp and is centered in the tube 1 by means of guides 11, 12,

and 13. Each of these guides isprovidcd with a carbon-bushing, as at 14, loosely nimbrecing the filsment. I

' The anode 10, to sy hichrofercncehas been made, is supported by a leading-in conductm 15, extendin through the uppcr'wnll of the co condensing-c ember- 22. The anode is sur rounded b a. hell or hood '16, which may be" of glass. 4 his hood iscles'ed at its top about the leading-in conductor 15 and flares out slightly at uits lower ed 0 17; 'This lower .ed e'is located close't'o't e point where the to e Iopensi'nto thecondensi n -chamber. When current isjig' lied tot e lam the solenoid 4 1s no: me ,f' o,el'o,tlraw t eiar mature 7 b, ow t e. surfacii ffifiie mercury.

'Thedrsft of vapor into the condens ising-charnberpess'es thro h thespccebetween the lower endof theshield lfi and ad jscent wells of the tubei. "Impurities are thus kept out of the 'condensin -chamber-2, and no resulting blackening or 'scoloratioifof theftnbel occurs. Such impurities as are l-i given off by the anode 10 are retained within the shield 16 andhave no harmful effect. Instead of locating the anode and its shield ently cles w at approximately the middle point of the Poiidensiiiq--ehuniher I may, if desired, mount them in t to mouth of the tube 1, where it opens into the eondensing-rhuinher. lhis ronstruotion is shown in Fig. l, in which the anode 18 and shield 19 are mounted in the mouth of the lampdubo ill. in other respeets the lump shown in Fig. l is the sumo us allUWll in Fig. 1, and therefore requires no further description.

What I claim as new, and desire to secure blv Letters Patent of the United States. is

1. Ina vapor electric apparatus, the eolnbination of an exhausted envelop provided with u condensing-ahainber, electrodes therefor, and a shield proterting one of the electrodes from the vapor progressing toward the mudensing-elnnnlwr.

2. In a vapor electric apparatus, the combination of an exhausted tube surmounted by a condensing-chamber, and a shielded electrode arranged where the tube opens into the oondensin -ehamher.

3. The com hination of an envelop or container provided with it eondensingehaniber, a vaporizahle electrode, and a shielded elee trode. located in thepnth taken hyvapor pussing to said eoinlensing-chnmher.

4. The combination of an envelo or container having a tube provided with an en- 30 lar elnent, a shield or hood closed at one end and having its other end located in the mouth of the tube, and an electrode inside of said shield or hood.

In witness whereof I have hereunto set my 5 hand this 27th day of May, 1904. V
